Afriend of mine told me about these gaskets, just wondering if anyone has used/heard of them.

They seem like a good idea: graphite to withstand the heat and compressible to seal better and maintain bolt torque.

never heard of the gasket (in my limited gasket knowledge). I would just stick with Percy's Deadsoft gasket. Have them on my car and haven't had any leaking
